I would not suggest the whole "boys" thing. Would not think you could find a place that would accept that liability-putting non-riders on random horses....just not a good idea.
Like the raffle and 50/50. Those are pretty routine ideas.
I have no idea what your facility/resources are, but, here are a few things that come to mind:
-have a horsey bake sale (or a regular one, or both)
-If you have the land, host a trail trial or a hunter pace type event. (we charge about $35/horse)
-Have a horsey wash (if you are at a large enough facility)
-if you all have the ability-maybe post signs in show barns for braiding, mane pulling, etc.
-host a tack swap. Our local 4-h just did one. THey got the local Tractor supply to allow them to set up in the parking lot. THey also advertised there a few weeks prior, and sold tables for $25/each to outsiders. They brought some of their horses, had them set up for kids to pet in pens, sold hot dogs, etc. Made it sort of like a carnival.With the right advertising (banners and fliers, etc) it could really be fun and pretty profitable.
